I found an article/review on Boris Groys by Benjamin Kunkel in the London Review of Books. Overall it’s probably accurate, but I didn’t perfectly recognize Groys in some of the more summary descriptions:
“Groys is…idealist in his belief that the radical artist can consciously understand and deliberately convey the meaning of his work…[he] advocates an art ‘functioning as political propaganda.'”
Kunkel gets to Groys’s belief in discursivity and the linguistic basis of art, but I think along the way he misses some of the irony.
